Flow thru shrink packaging equipment forms a shrink film package from a single roll of shrink film that has an overlapped shrink film seal underneath the package and a cross seal on the front and back sides of the package. Shrink bundler packaging equipment forms a shrink film package around the product from two rolls of shrink film which has cross seam across the front and back sides of the package and openings in the film package on the left and right sides of the package.

The heat from the heat shrink tunnel causes the film to shrink around the product forming a tight package around the product.
